Python output format

Question

When I am printing the following informatiom It looks really ugly. The text display is very long and you cannot really read it.

Code:

import psutil
print("Disk: ", psutil.disk_partitions())

The output I get is:

Disk:  [sdiskpart(device='C:\\', mountpoint='C:\\', fstype='NTFS', opts='rw,fixed'), sdiskpart(device='D:\\', mountpoint='D:\\', fstype='', opts='cdrom'), sdiskpart(device='E:\\', mountpoint='E:\\', fstype='', opts='cdrom'), sdiskpart(device='F:\\', mountpoint='F:\\', fstype='NTFS', opts='rw,fixed'), sdiskpart(device='H:\\', mountpoint='H:\\', fstype='NTFS', opts='rw,removable')]

In one long line! Is there a way to filter the output or display it on multiple lines?

Thanks for helping me :)

Answer 1

psutil.disk_partitinos() gives you a list of partitions on your systme.

Each element in that list is instance of sdiskpart which is a namedtuple with the following properties:

['count', 'device', 'fstype', 'index', 'mountpoint', 'opts']

You will have to process this list and format and display it the way you want using str.format() and print() .

Please refer to the psutil documentation.

A simple function that displays "disk information" in a "better way" could be something as simple as:

Example:

from psutil import disk_partitions


def diskinfo():
    for i, disk in enumerate(disk_partitions()):
        print "Disk #{0:d} {1:s}".format(i, disk.device)
        print " Mount Point: {0:s}".format(disk.mountpoint)
        print " File System: {0:s}".format(disk.fstype)
        print " Options: {0:s}".format(disk.opts)


diskinfo()

Output:

bash-4.3# python /app/foo.py
Disk #0 /dev/mapper/docker-8:1-2762733-bdb0f27645efd726d69c77d0cd856d6218da5783b2879d9a83a797f8b896b4be
 Mount Point: /
 File System: ext4
 Options: rw,relatime,discard,stripe=16,data=ordered

Answer 2

You could do something like this:

print("Disks:")
for disk in psutil.disk_partitions()):
    print(disk)

That should look like this:

Disks:
sdiskpart(device='C:\\', mountpoint='C:\\', fstype='NTFS', opts='rw,fixed')
sdiskpart(device='D:\\', mountpoint='D:\\', fstype='', opts='cdrom')
sdiskpart(device='E:\\', mountpoint='E:\\', fstype='', opts='cdrom')
sdiskpart(device='F:\\', mountpoint='F:\\', fstype='NTFS', opts='rw,fixed')
sdiskpart(device='H:\\', mountpoint='H:\\', fstype='NTFS', opts='rw,removable')
